<p>PROBLEM TO BE SOLVED: To provide a physical quantity detection circuit, a physical quantity detection device, an electronic apparatus, and a moving body in which an offset of a differential capacitance sensor can be adjusted at an analog stage.SOLUTION: Physical quantity detection circuits 110A-110C are connected to a differential capacitance sensor 10 (10X, 10Y, 10Z) including a first capacitance formation unit 41 and a second capacitance formation unit 42. The physical quantity detection circuits 110A-110C includes: a first differential signal line 121 to which a first electric charge is supplied from one end of the first capacitance formation unit 41; a second differential signal line 122 to which a second electric charge having a sign opposite to that of the first electric charge is supplied from one end of the second capacitance formation unit 42; an offset adjustment capacitance 130 that is set to a capacitance value based on an offset amount between fixed capacitances 41A, 42A of the first and second capacitance formation units, respectively; and an offset selection switch 140 (ASW3, ASW4) for connecting one end of the offset adjustment capacitance to either one of the first and second differential signal lines.</p> |
